Easiest way to get list of files in the server directory
提问by Jan Chalupa
I need to get array of all images (or simply of all files) in directory (e.g. www.example.com/images/). I prefer to use JavaScript but it's hard to make. So should I use PHP, meybe?
我需要在目录（例如 www.example.com/images/）中获取所有图像（或只是所有文件）的数组。我更喜欢使用 JavaScript，但很难做到。那么我应该使用PHP吗？
Could you please help me - I'm not good at this.
你能帮帮我吗 - 我不擅长这个。
Thank you very much!
非常感谢！

Javascript cannot fetch all files on a server, as it is a client-side langugage.
Javascript 无法获取服务器上的所有文件，因为它是一种客户端语言。
http://php.net/manual/en/function.glob.phpis what you need.
http://php.net/manual/en/function.glob.php正是您所需要的。
$all = glob('/path/to/dir/*.*');
$images = glob('/path/to/dir/*.{jpg,png,gif}');

I disagree with @mariobgr. If there is no server setting preventing a directory listing, then the html generated by requesting that directory can be parsed for the contents.
我不同意@mariobgr。如果没有阻止目录列表的服务器设置，则可以解析通过请求该目录生成的 html 的内容。
